Tested on: paFileDB 3.0 Final paFileDB 3.0 Beta 3.1 paFileDB 3.1 Final

Explanation:

paFileDB is a file management script that supports user file rating. It uses an SQL database backend. Multiple vulnerabilities exist due to the lack of checked input variables. The following exploits exist: - Modified 'id' tag allows users to submit unlimited ratings. - Hand-edited 'rating' tag allows users to submit ratings above 10 or below 0. - Both tags do not check for escape characters and will allow SQL injection.

Proof-Of-Concept Exploits:

http://target/pafiledb/pafiledb.php?action=rate&id=1[RANDOM]&rate=dorate&rating=10 Replace [RANDOM] with a random short string and the script will not be stop you from voting as many times as you like.

http://target/pafiledb/pafiledb.php?action=rate&id=1&rate=dorate&rating=1000 Submit file rating of 1000 out of 10. Drive rate up. Conversely, -1000 would have the opposite effect driving the rating down.

http://target/pafiledb/pafiledb.php?action=rate&id=1&rate=dorate&rating=` http://target/pafiledb/pafiledb.php?action=rate&id=`&rate=dorate&rating=10 SQL Injection vulnerability (exploit code not included)
